Barrick Gold’s Veladero mine, in Argentina, had three cyanide leaks between 2011 and 2012 that were contained by the mine’s control system, a spokesperson told Reuters on Sunday after local media published a government document describing the spills.
The three leaks happened long before last September’s Veladero cyanide spill, for which the Toronto-based company was fined $9.8-million. Tests by UN investigators in October showed that the leak had not contaminated local water supplies.
